There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - node-tar is a full-featured Tar for Node.js. Prior to version 7.5.11, tar (npm) can be tricked into
    creating a symlink that points outside the extraction directory by using a drive-relative symlink target
    such as C:../../../target.txt, which enables file overwrite outside cwd during normal tar.x() extraction.
    This vulnerability is fixed in 7.5.11. (CVE-2026-31802)

The remote Debian 11 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-4552 advisory.

    Package        : node-tar     Version        : 6.0.5+ds1+~cs11.3.9-1+deb11u3     CVE ID         : CVE-2024-28863 CVE-2026-23745 CVE-2026-24842 CVE-2026-26960                      CVE-2026-29786 CVE-2026-31802

    Multiple vulnerabilities have been discovered in node-tar, a Node.js     module to read and write portable tar archives.

    CVE-2024-28863

       Generating a large number of sub-folders can consume memory on the        system and even crash the Node.js client within a few seconds using        a path with too many sub-folders inside.

    CVE-2026-23745

       When preservePaths is false, the linkpath of Link (hardlink) and        SymbolicLink entries fail to be sanitized, allowing malicious        archives to bypass the extraction root restriction, leading to        arbitrary file overwrites via hardlinks and symlink poisoning via        absolute symlink targets.

       The fix for this issue introduces multiple of the following        vulnerabilties.

    CVE-2026-24842

       The security check for hardlink entries allows an attacker to craft        a malicious TAR archive that bypasses path traversal protections and        creates hardlinks to arbitrary files outside the extraction        directory.

    CVE-2026-26960

       An attacker-controlled archive can create a hardlink inside the        extraction directory that points to a file outside the extraction        root, enabling arbitrary file read and write as the extracting user.

    CVE-2026-29786

       An attacker-controlled archive can create a hardlink that points        outside the extraction directory by using a drive-relative link        target.

    CVE-2026-31802

       An attacker-controlled archive can create a hardlink that points        outside the extraction directory by using a drive-relative link        target.


    For Debian 11 bullseye, these problems have been fixed in version     6.0.5+ds1+~cs11.3.9-1+deb11u3.

    We recommend that you upgrade your node-tar packages.

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - node-tar is a full-featured Tar for Node.js. Prior to version 7.5.11, tar (npm) can be tricked into     creating a symlink that points outside the extraction directory by using a drive-relative symlink target     such as C:../../../target.txt, which enables file overwrite outside cwd during normal tar.x() extraction.
    This vulnerability is fixed in 7.5.11. (CVE-2026-31802)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of Atlassian Jira Service Management Data Center and Server (Jira Service Desk) running on the remote host is affected by a vulnerability as referenced in the JSDSERVER-16573 advisory.

  - File Inclusion vulnerability, allows an unauthenticated attacker to get the application to display the     contents of a local file, or execute a different files already stored locally on the server.     (CVE-2026-31802)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The version of node-tar installed on the remote host is prior to 7.5.11. It is, therefore, affected by a vulnerability:

  - node-tar is a full-featured Tar for Node.js.
